The rolled-paper holder includes a bottom wall having a first contact bottom portion and a second contact bottom portion, a first contact side wall, and a second contact side wall, wherein the sidewalls are substantially parallel to each other. The partitioning member includes a third contact side portion arrangeable in parallel to the first contact side wall and the second contact side wall, a third contact bottom portion that is brought into elastic contact with the bottom wall at a predetermined elasticity and may be stopped there by engagement, and a coupling portion that may be coupled to the second contact side wall.

Abstract: A miniaturized rolled-paper holding mechanism is capable of detecting the residual quantity of rolled-paper in both horizontally and vertically installed states of a printer. The rolled-paper holding mechanism includes a rolled-paper holder, a holder cover, a positioning member, and a residual-paper-quantity sensor. The positioning member is structured such that, as the holder cover is opened or closed, the inclination angle of the positioning member is varied with respect to a second-bottom-portion inclined surface formed in the rolled-paper holder. Further, a second positioning groove—which, when the holder cover is closed, can be contacted with rolled-paper R having a given diameter—is formed between the positioning member and the second-bottom-portion inclined surface of the rolled-paper holder.

Abstract: A miniaturized rolled-paper holding mechanism (10) which is capable of detecting the residual quantity of rolled-paper in both horizontally and vertically installed states of a printer. The rolled-paper holding mechanism (10) includes a rolled-paper holder (21), a holder cover (41), a positioning member (51), and a residual-paper-quantity sensor (61). The positioning member (51) is structured such that, as the holder cover (41) is opened or closed, the inclination angle of the positioning member (51) is varied with respect to a second-bottom-portion inclined surface (29) formed in the rolled-paper holder (21). Further, a second positioning groove (31)-which, when the holder cover (41) is closed, can be contacted with rolled-paper R having a given diameter-is formed between the positioning member (51) and the second-bottom-portion inclined surface (29) of the rolled-paper holder (21).

Abstract: There is disclosed a terminal device. A paper roll cover is pivotally connected at its proximal end portion on a rear end portion of a paper roll receptacle portion so as to pivotally move into an open position where the paper roll cover is inclined slightly rearwardly. Position limiting members are provided on the inner side of the paper roll cover for holding a paper roll in registry with a paper insertion slot when the paper roll cover is in the open position. The paper roll is supported by the position limiting members, so that paper can be drawn out from a lower side of the paper roll by both hands, and can be positively inserted into the paper insertion slot. When the paper roll cover supporting the paper roll is pivotally moved into the closed position, the paper roll is caused to roll into the paper roll receptacle portion, so that the drawn-out portion of the paper is again wound on the paper roll.

Abstract: In a tape printer apparatus, tape cassettes containing tape members of different widths are selectively mounted, and input printing data is printed on the tape member of the mounted tape cassette. The tape cassettes are provided with notches indicating the widths of the contained tape members. The presence or absence of the notch of the mounted cassette case is detected by ON or OFF of switches disposed in a cassette mounting portion of an apparatus case. Based on a result of this detection, the tape width is determined, and a printing matching with the tape width is performed.

Abstract: A web feeding and handling system for feeding a two-ply web to a printer and winding one of the webs about a take-up spool and directing the remaining web into a cutter. The printer and web feed system are arranged in a housing having an access opening sealed by a door. The printer and a feed roller holder assembly are mounted upon a plate movable between a position enhancing access to the printer and supply roll holder to facilitate supply roll replacement and feeding the web into the printer, and a position placing the printer web output end closer boa cutter and a take-up assembly mounted upon the door and including a rotatable drive disk and a spindle support which support a removable spindle to wind up one web. A motor drive mounted within the housing engages the drive disk when the door is closed and is disengaged from the disk when the door is open. The supply roll holder receives and automatically aligns the web to prevent skewing.

Abstract: A color printer according to the present invention includes a clutch means, an urging member and a positional alignment mechanism. The clutch means is used for engaging and disengaging a driving force used to move a paper holder means. The urging member (e.g., a spring) is used to urge the paper holder means in a direction opposite to the printing direction. The positional alignment mechanism is used for mechanically determining the position at which printing is to start on the paper when the paper holder means is disengaged from the driving force by the clutch means and is urged by the urging member in the direction opposite to the printing direction.
